This "TD-only" scoring system does still exist and usually only with really old leagues that never wanted to change. Some of those leagues may use other nuances like deducting for interceptions and making distance scoring matter. Defenses can also be made valuable with other categories but this is just the NFL scoring considered. Sort of like a LAG for the NFL.

Quarterbacks - Other than when a player (Tomlinson) has a NFL record-year, QBs are the scoring king in this system and owning a top three player is absolute gold. After about the third best, there is a much less pronounced decline through the rest but the line continues in the same decline beyond that point. Having a top QB is paramount to winning this league. This is like the Manning league.

Running Back - This position skewed so highly with Tomlinson's record-setting year but dismissing that aberration of all-time, running backs are not as valuable as QBs but more so than any other position. And the decline is pretty sharp though the first dozen or so before flattening out. Owning a top ten back in this league is still a pretty big advantage.

Tight Ends - While it is nice to get any points in this league, tight ends are not particularly valuable and Gates deserves to be an early pick if only because after him it gets so spotty with TD-only considered.

Defenses - The top ten defenses decline somewhat sharply but after that there was little difference (or many touchdowns for that matter). The harder part of this position in this scoring is that all that matters are touchdowns. Owning a special teams like Chicago with Devin Hester played huge last year since he scored six times on returns.
